目的膳食质量指标（DQI）容易受到疾病背景的影响，因此针对各种疾病调整现有指标至关重要。目前还没有研究将DQI用于2型糖尿病患者。我们的目的是调整健康饮食指数，并评估其对伊朗2型糖尿病（T2DM）患者的有效性。方法在横断面研究中，对489例成年T2DM患者进行分析。我们改编了HEI，并使用构念效度来评估其效度。建构效度评估采用168项半定量食物频率问卷（FFQ）。采用一般线性模型评估适应HEI分数与人口统计学特征、人体测量指数、身体活动、食物和营养摄入之间的关系。结果对489名受试者（163名男性，326名女性）进行了适应性HEI检查。研究结果表明，老年受试者的平均适应HEI得分高于年轻受试者。然而，仅在女性中有统计学意义（p = 0.01）。受教育程度越高的女性得分越高（p < 0.001）。男性适应HEI评分的最高平均值与不吸烟者有关。随着体育活动量的增加，男女平均得分均升高（p < 0.05）。此外，与BMI较低的男性相比，BMI较高的男性的适应性HEI平均得分降低（p = 0.001）。结论适应型HEI可有效鉴别T2DM患者的饮食质量。年龄较大和受过高等教育的妇女非常坚持高质量的饮食。调整后的DQI与较高的身体活动水平和较低BMI的非吸烟糖尿病男性有关。
Purpose As diet quality indices (DQI) are likely to be influenced by disease background, adapting the existing indices for each disease is crucial. No study has been adapted a DQI for patients with type 2 diabetes. We aimed to adapt healthy eating index and assess its validity for Iranian patients with type 2 diabetes mellitus (T2DM). Methods In this cross-sectional study, the analysis was conducted on 489 adults with T2DM. We adapted HEI and assessed its validity using construct validity. Construct validity was assessed using a 168-item semi-quantitative food-frequency questionnaire (FFQ). General linear model was used to assess associations between adapted HEI scores and demographic characteristics, anthropometric indices, physical activity and food and nutrient intakes. Results Adapted HEI were examined on 489 subjects (163 men and 326 women). Findings showed that in older subjects the mean adapted HEI score was greater than the younger ones. However, it was significant only in women (p = 0.01). Women with higher education level obtained the greater score (p < 0.001). The greatest mean score of the adapted HEI score in men was related to non-smokers. The mean score in both genders were raised following the increase in physical activity level (p < 0.05). Moreover, a reduction in the mean score of adapted HEI was observed in men with higher BMI compared to those with the lower one (p = 0.001). Conclusion Adapted HEI could successfully discriminate diet quality in patients with T2DM. Older and high-educated women were adhered greatly to high quality diets. The adapted DQI linked with greater physical activity level and non-smokers diabetic men with lower BMI.
